The carbohydrate content of a white potato is primarily determined by its size. As a starchy vegetable, carbohydrates are its main macronutrient.
A medium-sized white potato (approximately 170-200 grams or 6-7 ounces), whether raw or cooked plainly (e.g., baked, boiled), generally contains around 30 to 40 grams of total carbohydrates.
A large raw white potato (approximately 290-300 grams or about 10 ounces), with flesh and skin, can provide approximately 55 to 65 grams of carbohydrates. For a potato of this size, carbohydrates may constitute 85-90% of its total caloric content.
Key Considerations:
- Size Variation: Carb content scales directly with the potato’s weight. A smaller potato (e.g., 100g) will have proportionally fewer carbs.
- Preparation Impact: Plain cooking methods like baking or boiling do not significantly alter the potato’s inherent carbohydrate amount. However, added ingredients in dishes such as french fries (due to batter or absorption of oil, though oil itself is fat) or creamy mashed potatoes (milk, butter) will change the overall carbohydrate and calorie count of the meal.
- Nutritional Profile: Beyond carbohydrates, white potatoes, especially when consumed with their skin, are a good source of dietary fiber. They also provide essential nutrients like potassium, vitamin C, and magnesium.
